Outlook 2007: Out of Memory or system resources

Posted on 2011-10-03
Last Modified: 2012-05-12
User running win 7, outlook 7

Error dialogue: "Out of Memory or system resources. Close some windows or programs and try again" see image

I have carried out full Windows maintenance, no spyware/viruses, carried out an Office Repair (via program features), ccleaner. No unusual Outlook add-ins

User says: "Mostly happens when forwarding. Except on Friday I could not send some emails. I don’t why I managed to send some and not others – it didn’t appear to have anything to do with the content/size."

I know that this messages is fairly common and there are posts here and elsewhere about it, but nothing really pointing clearly to the cause or fix.

Any suggestions?

    1st check that you have the latest SP Installed for Office 2007

    otherwise, I have seen this issue several times in the past.
    It is usually created by trying to use the Send To, or Email Feature in Other applications or by right clicking on a file and using send to and or Users of MAPIMail.

    In each case the MAPI Dlls were found to be corrupt and or broken and needed to be recreated.
    Once recreated, all was working fine.

    By any chance the Outlook 32 bit and\or 64 bit version is causing the confusion?

    >> Any body else facing the same issue?
    If yes, need to suspect the CD-media or the imaging technique to be at fault
    If not, want to try the same activities "forwarding items"...when outlook is launched as "Outlook /safe"

    Thanks, apache09. I had found this resource which advises to rename Riched20.dll and then doing a Repair (from Program features). So far the problem hasn't recurred. So yes seems it was a dll problem.

    See the comment at the bottom.

    e_aravind: I'm not really sure what you mean? This Outlook was installed over a year ago. It's 32bit.
